Vue-instantsearch - createServerRootMixin - SSR - composition API

Hey,

we currently use vue-instantsearch and want to activate the SSR with nuxt:

As described in the docs, we have to call createServerRootMixin with a searchclient and an indexname.
Is there a way to make the indexname dynamic, based on the given language?

Maybe someone of you had the same challenge.

Best regards
Philipp
